A Fox News host notorious for his skepticism made a controversial suggestion about climate scientists during an on-air debate this week.

Fox's Brian Kilmeade became testy during his radio show Tuesday when a caller argued that almost all scientists believe climate change is a real phenomenon, according to Raw Story.

The caller, named "John," was referring to the portion of President Barack Obama's inauguration address in which he said, "We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations."

John called climate change, the "most important thing we need to be concerned about," to which Kilmeade replied sarcastically, "This morning it snowed, only because there was pollution in China."

When John protested that 98 percent of climatologists say climate change is real, Kilmeade shot back: "You mean the corrupt ones? You mean the corrupt ones who admit they skew their findings?”

A study published in the Proceedings of the National Academy of Sciences in 2010 surveyed 1,372 climate researchers and found that "97–98 [percent] of the climate researchers most actively publishing in the field support the tenets of [anthropogenic climate change] outlined by the Intergovernmental Panel on Climate Change."

Nearly a dozen of the world's most prominent national science academies have acknowledged that the world's climate is changing as a result of increasing atmospheric concentrations of greenhouse gases, mostly from the burning of fossil fuels.

Kilmeade, however, has remained a staunch skeptic.

In October, he called global warming a scam in an interview with Dr. Alex Berezow.

Kilmeade isn't the first Fox News personality to dispute the scientific consensus behind climate change. In May, Fox News contributor Deroy Murdock said there were "hundreds of thousands" of scientists still debating the issue.

While Murdock's claim does not seem to be backed up by fact, a study conducted by The Yale Project on Climate Change Communication found that while 70 percent of Americans believe the world is warming, only about half accept its human origin, NPR reports.
